The engineering behind the #GearFit2

The all-new GPS-enabled sports band, the Gear Fit2, is the latest product in a long line of cutting-edge wearables from Samsung. We sat down with the engineers who were deeply involved in the development of the Gear Fit2 to discuss how they worked together to set a new standard for fitness wearables.

Q. When it comes to hardware, what is most notable about the Gear Fit2?

Chaekyu Choe: To improve performance as a sports band, we added a GPS, an application processor (AP) on the level of a smartwatch, and improved sensors.

With an embedded GPS, the Gear Fit2 allows users to go out and more accurately track their activities, like walking or running, without bringing along their smartphones.

By separating the LED and photodiode, both of which are needed to measure heart rate, we were able to use a bigger photodiode and enhance heart rate accuracy. Also, the Gear Fit2’s barometer sensor, which is now about 10 times more precise, made it possible to measure elevation accurately enough to know how many stairs people climbed.

Q. How were you able to embed full GPS capabilities?

John Kim: The antenna has to receive the satellite signals but getting it to perform well was a challenge. Antennas work better when they are further from the human body. To address this issue we created a hybrid antenna. In order to place the antenna as far as possible from the wrist, the antenna was embedded inside the display and an assistant antenna was installed in another area, thus forming a dual antenna that enhanced performance.

Q. How did you improve battery efficiency?

Hyukbeom Kwon: During the development, we found that power consumption can be reduced by controlling how often the GPS is accessed according to signal intensity. In general, exercise that requires GPS data is normally done outdoors where GPS signals are usually strong. So, we decided to make it turn on and off using a radio frequency blocking function.

Through this low-power GPS technology, we were able to reduce power consumption significantly, so it uses about one-fourth the power of a regular GPS device.

Q. How does the automatic workout recognition work? And were there any challenges in developing this feature?

Wonhee Lee: The accelerometer sensor is used to identify the user’s motion first, and then the gyroscope sensor detects the direction and type of movement. The Gear Fit2 can detect five types of workout– walking, running, cycling, elliptical trainers and rowing machine– and automatically recognizes when those activities have been done for at least 10 minutes.

As there wasn’t any systematized database telling us “this workout is such-and-such,” we had to understand the data and figure out how to use it to identify each type of activity ourselves. To identify the exact type of workout, we had to get data from as many people as possible– because even for the same workout, the speed and intensity differ greatly depending on one’s age, height, gender, and so on.
